Lesson 5 of 5

Multi-effects and modelers

You don't have to build your tone from single pedals. Multi-effects units and amp modelers put a whole rig in one box.

Three approaches

  • Pedals: one effect per box. Easy to tweak and swap, with great hands-on feel. But cables, power and space add up.
  • Multi-effects: many effects in one unit, usually with presets. Some include basic amp sounds too. Cheaper per effect and easy to carry.
  • Amp modelers: digital recreations of amps, cabinets and mics, plus effects. They can go straight to a PA, an audio interface or headphones.

The main names

Line 6's POD, launched in the late '90s, made amp modeling mainstream for home recording. Its Helix floor units and smaller HX pedals are now common on professional stages. Boss covers every level with its GT, GX and ME series, mixing its classic effects with amp models.

Fractal Audio's Axe-Fx and floor units are known for deep, detailed editing and are popular with touring players. Kemper takes a different route: its Profiler captures the sound of a real amp you run through it. Neural DSP's Quad Cortex brought a touchscreen floor unit with its own capture feature. Headrush also uses touchscreens for quick editing, and Zoom makes budget-friendly, compact multi-effects that work well as a first unit.

Pros and cons

Single pedals Multi-effects / modelers
Hands-on feel Excellent Menus and presets
Consistency Varies with power and cables Same sound every night
Getting started One or two pedals at a time One bigger purchase
Flexibility Swap anything Huge variety in one box
Learning curve Gentle Can feel deep

Hybrid rigs

Many players mix both. A common approach is to keep a favorite drive pedal in front of a modeler, or to use a modeler only for delay and reverb in an amp's effects loop. The "four-cable method" goes further: it lets one unit place some effects before the amp's preamp and others in the loop.

Start simple. Pick one amp model and three effects, learn them well, then expand.

Checkpoint

Move on when you can do all of these.

  • Explain the difference between a multi-effects unit and an amp modeler
  • Name three modeler or multi-effects brands and one product from each
  • List two pros and two cons of an all-in-one unit compared with single pedals
  • Describe one way to build a hybrid rig with pedals and a modeler
